72SE c The assumption that there is no ground state feeding will lead to a
72SEac 5% direct feeding of the 1637 keV level with J|p=4+, as well as a
72SEac direct feeding of about 20% to the first 2+ levels. As a result, the
72SEac ground state of {+72}Br could be characterized as having J|p=3+. A
72SEac recent experiment by Piqueras et al (2003Pi03) points to a J|p=1+ for
72SEac the ground state {+72}Br based on the decay of {+72}Kr. This result
72SEac will in turn mean that the ground state feeding of {+72}Se is not
72SEac zero. In consequence, all gamma and beta intensities, as well as log|
72SEac {Ift} values should be taken as approximate
72SE c The decay scheme is based on |g|g coincidence measurements with
